A force spokesman said: "Kent Police was contacted by a member of the public from outside the county around election fraud due to speculation on social media in South Thanet.

"Initial inquiries by officers have been carried out and so far no evidence of electoral fraud has been found."

Thanet District Council said in a statement: "A single complaint has been lodged with Kent Police by a member of the public, from outside of the county, with concerns around the Thanet parliamentary election - following speculation on social media.

"Thanet's parliamentary boundary is larger than the district boundary - extending into the Canterbury and Dover area - so comparing the parliamentary and district election results is misleading. There were no lost or stolen ballot papers."

Mr Farage last week attempted to resign following his defeat at the polls and the party's failure to win more than one seat despite its large share of the popular vote.

But the party rejected his resignation, saying the election campaign had been a success.
